Diagnosis:
A qualified technician will need to diagnose the cause of the P0700 code. This will involve:
- Scanning the computer for trouble codes
- Checking the transmission fluid level and condition
- Testing the transmission input/output speed sensor
- Checking the transmission solenoid
Repair:
The repair for the P0700 code will depend on the cause of the problem. In some cases, simply adding transmission fluid or changing the fluid filter may be enough to fix the problem. In other cases, the TCM or transmission solenoid may need to be replaced. In severe cases, the transmission may need to be rebuilt or replaced.
